SPECIFICATION forming part of Letters Patent No. 322,249,6atedJu1y 14, 1885.

Application filed Februaryflfi, 1885. (N model.)

To all whom it may concern.-

Be it known that we, Isaac BROKAW andWES- LEY BUTLER, both of Litchfield, Montgomery county, State of Illinois, have invented a certain new and useful Improvement in Straw- Stackers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a side view of the machine. Fig. 2 is a top view of the lifting-frame. Fig. 3 is a side view of the lifting-frame in its low: er position, and Fig. 4 is a side view of the same somewhat raised. Fig. 5 is a detail section at 5 5, Fig. 2. Fig, 6 is a top view of the carrier proper extended, and Figs. 7 and 8 are, respectively, a side view and a longitudinal section of the same.

The device is shown as supported on a carriage separate from a thrashing-machine; but it may be supported as an extension of the thrashing-machlne.

The supporting-wheels are shown at 10 and the carriage-frame at 11.

12 are standards firmly secured to the frame 11 and forming guides for the sash-frame 13, upon which the carrier-frame is supported. The upper end of the sash-frame is braced by 7 a movable brace-frame, 14, hinged at 15 to the sash,and having its lower end working longi-- tudinally in guides 16 of the supportingframe 11.

Thesash or sash-frame 13 is raised and low ered by means of the following mechanism: 17 is a shaft, which may be turned by a winch upon its square end 18,and which has a screwthreaded part, 19, working in a nut, 20, fixed to the cross-bar of the brace-frame. Upon this shaft 17 (which will hereinafter be referred to as the operating-shaft) is a gear-screw, 21,whichengages a Worm-gear wheel, 22, fast upon a shaft, 23, (which will hereinafter be referred to as the winding-shaft,) which carries pulleys or drums'24, to each of which is secured one end of a chain or cable, 25, each chain passing over a pulley, 26, turning on an arbor fixed to the upper part of the standards,

12. From these pulleys the chains extend downward and have their ends attached to the 'lowerpartof the sash 13. The arrangement is such that as the operating-shaft 17 is turned the foot of the brace-frame is moved horizon tally and the sash is moved vertically, the movements being so proportioned that the brace-frame shall support thesash in a vertical position in all positions.

It will be observed that as the sash is raised,

ment of the sash; or the guideways 16 may be curved upward toward the sash so as to lift the lower end of the brace-frame as it approaches the sash and with accelerating speed. Segments may be used in place of the drums In place of using eccentric drums or segments, the drums may be made conical and of small diameter. 1

27 is a shaft extending transversely from one side of the sash to the middle of the same,

and having upon it a sleeve, 28, which is connected to the shaft by a spline, so as to turn with the shaft but to have endwis'e movement thereon. This sleeve carries right and left gear-screws at 29, either of which may be brought into engagement with the screw-gear wheel 30, so as to cause the rotation of the wheel in either direction. The wheel 30 is upon an upright shaft, 31, carrying a loose pinion, 32, upon whose upper side are studs 33, which are engaged by a cross-bar, 34, ex-

tending from the shaft. Thearrangement is such that the shaft 31 has a certain amount of lostomotion in the pinion, so that when the rotation of the wheel 30 isreversed the shaft shall turn within the pinion while the bar or pin 34 is moving from one to the other of the studs 33. The pinion engages a cog-sector,

35, which is fast to the, oscillating straw-carrier frame, so as to impart the oscillating movement to this frame;and the times of the. 00 lost movements of the shaft in the pinion are i when the carrier has reached an extreme in its side movement, and just before its movement is reversed.

Except as relates to the device for giving lost movement of shaft31 in pinion 32, the train of gearing for imparting oscillatory movement to the straw-carrier proper is similar to that described in the specification to our application filed October 13, 1884, Serial No. 145,381, and will not be here particularly described. The machinery for driving the raddle and for extending the raddle-frame are also similar to those described in said application. At the inner end of the shaft 27 is a bevel-wheel, which engages a similar wheel at the lower end of a vertical shaft, 36, passing up centrally through the sash-frame and having at its upper end a bevel-wheel, 37, engaging a like wheel, 38, upon a horizontal shaft, 39, whose outer end carries a sprocketwheel, 40, by which the raddle-driving roller 41 is actuated by means of a drive-chain (not shown) engaging wheel 42.

The straw-carrying frame is composed of a part, 43, having hinge-connection 44 to the sash 13, and a part, 45, extensible upon the part 43. The part 45 has tubes 46, extending along its sides, and which work in tubes 47, extending along the sides of the part 44, the tubes 46 being perforated along the lower sides, so as to be engaged by the sprocket-teeth of wheels 48, so that by the rotation of the wheels the part 45 is moved inward and outward. This construction is similar to that described and claimed in my application hereinbefore referred to. The wheels 48 are upon a shaft, 49, carrying at one end a bevel-wheel, 50, engaging a bevel-wheel, 51, upon a shaft, 52, which is turned by a handcrank, and held in position by means of a cogwheel, 53, and a dog engaging therewith, or by any other suitable means.

The raddle is composed of endless belts 54 and transverse slats 55, and is supported on the drive-roller 41 and roller 56 at the outer end of the part 45. The raddle works upon close floors 57 and 58 of the parts 43 and 45. These floors are made with a bevel-j oint at 59, so that they may be in the same plane when extended, as shown in the drawings. The beveled lip of the outer part, 45, overlaps this lip of the part 43, so all descending grain is carried over the joint, and the part 45 will ride over the part 43 when retracted.

60 is a box which receives the loose hanging part of the raddle when the part 45 is retracted.

61 is a derrick-frame, hinged at 62 to the frame 11, and supported at the proper angle by a guy-rope, 63, extending to the frame of the thrashing-machine.

64 is a grooved pulley at the top of the derrick, which carries a rope or chain, 65, one end of which is connected to a bail, 66, whose arms are connected to the outer end of the part 43 of the straw-carrier. The other end of the 6 5 rope is connected to a Windlass, 67, with usual ratchet wheel and pawl, 68 69, to hold the car-' rier at any desired elevation at the delivery end.

WVe claim- 1. In a straw-stacker, the combination, with the main frame and the carrier, of a lifting frame or sash upon which said carrier is supported, and a brace-frame, substantially as described, hinged to the said sash for bracing it, as set forth.

2. The combination, with the main frame, the brace-frame, the lifting frame or sash, and the straw-carrier supported thereby, of a winding mechanism for moving said sash, and connection between said winding mechanism and the brace-frame whereby said sash and braceframe are moved synchron0usly,'as explained.

3. The combination, with the main frame, the lifting frame or sash, the brace-frame, and the straw-carrier supported thereby, of a winding-shaft having connection with said sash, an operating-shaft connected to the winding-shaft by gearing, and having a screw-threaded portion, and a nut on the brace-frame.

4. The combination, with the main frame 11, the standard 12, the pulley 26, the lifting frame or sash 13, and the straw-carrier supported thereby, of the brace-frame 14, hinged to the sash 13, the winding-sh aft 23, having the worm-wheel 22, the cord '25, the operatingshaft 17, having the worm-thread 21 and screwthreads 19, and thenut 20 on the brace-frame,

all constructed and arranged to operate substantially in the manner and for the purpose set forth.

5. The combination, with the sash, a shaft journaled vertically therein, the circular rack secured to said shaft, and the carrier, of the second vertical shaft, having the pin project ing laterally therefrom, and the pinion mounted loosely upon said shaft and adapted to be engaged thereby, substantially as set forth.
